CONVEYER-BELT.

SPECIFICATION forming part Of Letters Patent N0. 705,876, dated July 29,1902. Applioation' filed May 31, 1902 Serial No. 109,601. (No model.)

To all whom it may concern.-

7 Be it known that I, WILLIAM J. SELLEOK, a citizen of the UnitedState's,residing at Riven side, county of Fairfield,State ofConnecticut, have invented a certain new and useful Improvement inConveyer- Belts; and I declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it pertains to make and use the same, referencebeing had to the accompanying drawings,

which form a part of this specification.

My invention relates generally to convey: ers, and more particularly toendless flexible conveyer belts which are given a troughshapedcross-section while carrying the material.

In order toprevent the material carried. by the conveyer from fallingoff the side edges thereof, it is desirable to provide in-' clinedguides'beneath theconveyer-belt to maintain the sides at a higher levelthan the center thereof. The transverse bending of the belt necessarytoincline its sides results in the belt soon Wearing outand breakingalong the lines between the central and side portions. to constructconveyer-belts with a central horizontal section andsidesections adaptedto be inclined with respect to the central sec-' tion to form a trough.Theside sections have either overlapped the edges ofthe cen-.

tral section and been secured thereto by rivets passing through theoverlapped portions or strips have been interposed between and securedto the adjacent edges of the central and side sections. It isevident,=however, that the objection above noted; is not avoided ineither of theconstructionsmemf It has been proposed heretofore the wearto which similar belts heretofore constructed have been subjected.

A further object of myinvention is to provide a conveyer-belt which willbe simple in construction, inexpensive in manufacture, and durable andefficient in use.

My invention, generally stated, consists in a conveyer-belt composed Iof a central and side sections flexibly unitedat their adjoining edgesby interlocked lacings.

My invention willbe more fully described hereinafterwith referenceto theaccompanying drawings, in which the same is illustrated as embodied in aconvenient and practical form, and in which- Figure 1 isacross-sectionshowing my conveyer-be1t supported by guide-rollers; Fig. 2,

a fragmentary plan view of my-improvement, and Fig. 3 an enlargedsectional fragmentary view showing the means for uniting the adjoiningedges of the central and a side section.

Similar reference characters are used to indicate similar parts in theseveral figures of the drawings.

Reference-letter A designates the central section of the conveyer-belt,to the side edges of which are flexibly secured side sections A and ASuitable guides are provided for supporting the central section A in ahorizontal position and maintaining the sidesections A and A in inclinedpositions, so as to impart to the conveyerbelt a trough-shapedcross-section, thereby preventing the material which is carried'on thebelt from falling oif of the sides thereof. -In Fig. l of the drawings Ihave indicated a central cylindrical roller B for supporting the centralsection A of the conveyer-belt, while side rollers B and B support theside sections A and A of the conveyer-belt in the inclined positionsindicated. The roller B is suitably journaled in the com veyer-frameas,forinstance, by means of concentric pins b,.while similar pins 1) and brotatably support the inclined rollers 13 and B v In order that the sidesections may freely move relatively to the central section withoutbending either the central or sidesections, I have provided lacingswhich pass through openings in the adjoining edges of the sections andwhich serve as hinges to permit the relative movement between the sideand central sections of the conveyer-belt. A lacing a, preferably in theform of a spiral, passes through each edge of the central section atcomparatively short intervals, as indicated in Fig. 2. A similar spirallacing a passes through the inner edge of the side section A atintervals corresponding to the spaces between the convolutions of thespiral lacing a. The portions of the spirals a and a which projectbeyond the edges of the respective sections are overlapped, so as toform a series of registering loops, through which is passed a flexiblewire or, preferably, a leather thong O. A spiral lacing a passes througha series of perforations in the inner edge of the side section A toengage a spiral lacing a, secured to the adjoining edge of the centralsection A. The projecting portions of the convolutions of the spirals aand a overlap, so as to form a passage, through which is inserted aleather thong 0 Before the leather thongs C and C are inserted throughthe overlapped lacings the latter are preferably flattened, as indicatedin Fig. 3, to form a passage-way of the requisite size to receive thethongs O and C The lacings are securely held in the edges of thesections of the belt and are not required to move in the openingstherein when the side sections assume the inclined positions to form atrough-shaped cross-section. The movement of the side sections withrelation to the central section is permitted by the movement of theoverlapped lacings with respect to each other. W'hilo the side sectionsmay freely move into the requisite inclined positions, they are rigidlysecured to the central section owing to the thongs O and G which coupletogether the overlapped lacings.

The material of which the sections of the conveyer is formed may beleather, rubber, cloth, wire, woven fabric, or any other suitableflexible material. The lacin gs a, a, and a are preferably formed ofwire.

From the foregoing description it will be observed that I have inventeda conveyorbelt capable of assuming a trough-shaped cross-section tosupport the carried material tions, of a hinge flexibly uniting saidsections composed of parts movably joined together and rigidly securedto the adjoining edges ofsaid sections.

2. The combination with aconveyer-belt composed of a plurality oflongitudinal sections, of lacings passing through the adjoining edges ofsaid sections, and means for flexibly nnitingsaid lacings.

3. The combination with a oonveyer-belt composed of a plurality oflongitudinal sections, of coil-spring lacings passing through each ofthe adjoining edges of said sections,

and a thong extending through the overlapped convolutions of thelacings.

4:. The combination with a conveyer-belt composed of a plurality oflongitudinal sections, of coil-spring lacings having ellipticalconvolutions passing through the adjoining edges of said sections, theprojecting portions of said convolutions being overlapped, and a leatherthong extending through the registering overlapped convolutions of saidlaclugs.

5. In a conveyer-belt, the combination with central and side sections,of a hinge flexibly uniting said sections composed ofparts movablyjoined together and rigidly secured to the adjoining edges of saidsections.

6. In a conveyor-belt, the combination with central and side sections,of lacings passing through the adjoining edges of said sections, andmeans for flexibly uniting said lacings.

In testimony whereof I sign this specification in the presence of twowitnesses.

WILLIAM J. SELLEOK.
